Problems solved by technology
[0004] When using the first method to meet the installation of different arm lengths, to provide seven different lengths of steel wire installation ropes will directly lead to high costs for users and cause waste of resources. There are six sections of steel wire ropes that are idle, and the second method is adopted. It is inconvenient to install and use due to the large quality of the connecting plate, and because the length difference of the five-section steel wire rope is not obvious, it is easy to install wrongly during use. too high

Embodiment Construction
[0028] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0029] Such as Figure 1 to Figure 5 As shown, according to an embodiment of the present invention, the steel wire rope assembly includes a multi-section steel wire rope that can be combined and connected in sequence, a connector 20 and a rope length switching device 30, and both ends of the steel wire rope and the connector 20 have a connection structure, and the rope length switching device 30 At least one end of the steel wire rope has a winding part on which the steel wire rope is wound. The connection length of the steel wire rope is adjusted by the rope length switching device 30 , and the multi-segment steel wire rope, the connector 20 and the rope length switching device 30 are selectively c...

The invention provides a steel wire rope component and a tower crane containing the same. The steel wire rope component comprises multiple sections of steel wire ropes, which can be combined and sequentially connected, and a rope length switching device (30), wherein connecting structures are arranged at the two ends of the steel wire ropes, and a winding part for enabling the steel wire rope to wind is arranged at at least one end of the rope length switching device (30). The steel wire rope component disclosed by the invention has the advantages of simple structure, convenience in mounting and use, capability of realizing the combination of multiple lengths with the fewer steel wire ropes and lower cost.
Description
technical field [0001] The invention relates to the field of hoisting equipment, in particular to a wire rope assembly and a tower crane including the wire rope assembly. Background technique [0002] At present, in the installation of the boom of domestic boom tower cranes, compared with different types of tower cranes, there are mainly two structures for the installation of steel wire ropes. One is to provide different lengths of steel wire ropes for different arm lengths. Take a tower crane with seven different arm lengths as an example, the user needs to purchase seven sections of wire ropes, and during installation, use wire ropes of different lengths to connect them at designated positions for installation. [0003] Another way is to design multiple sections of connecting steel wire ropes with shorter lengths, and to install some sections of them for installation with different jib lengths. For example, five sections of wire rope are provided and four connecting plate...
